Ignition coil MSD or BERU

I \"upgraded\" my ignition coil to an MSD SS Coil after my OEM Bosch began to fail at 110,000 miles. It's a rare opportunity to upgrade a part on a car & actually spend less money on the part. & for whoever that made 900 HP on the stock coil, I'd bet money the MSD would make more lol I'm not trying to be an @ss, I just see this so much on the Vortex. Someone inquires about something, EX) Headers, UD Pulleys, Light Weight Flywheels, etc, & you have atleast 10 @ssholes that say they don't work. I'm done ranting

A factory coil is not wound well enough to keep a continued full spark at higher rpms. Upgrading my coil to the MSD blaster SS made a huge difference above 4,000rpms. Throttle response is much crisper and the rpm's are a lot smoother because the upgraded coils can recharge and send spark out faster than the factory unit. Granted I spin my car to about 6,000rpms every time I drive it so I needed the extra spark. If you're just looking for extra power your're not going to find it in a coil. You will find better fuel economy (I gained 20 miles a tank) a cleaner burn 27ppm on my emissions test total and smoother revs at high rpms.
